The questions not quite clear. Could u send ur code to abdij_b@hotmail.com with relevent comment in the code. I donot get what u mean by outside the doc. How have u declared the variable? What is the scope where do u want to use it? Lot of quetions unclear.

I really appreciate your response, however I my not have been clear in my question. I like to manipulate (write or read) the variable in the data class from any class in the program (generic or MFC). Any idea what would be the best way. It seems my data get lost from one class to the other.

My method is globally accessible from any class. Your original example declared an instance in a function. This loses scope once you exit the function. You could make it static within the function to retain any values you may have set, but then that instance would only be available in the function. You could create a container class with a static instance of data. But, this is just a variation of my example where the CWinApp derived class is the container.

It could be if you put the proper code in your data class accessors. You'd want to have a PutAge() and GetAge() member function that messed with the actual data from within critical section protectors. I'm no expert on that, but there is code in the MFC code that could serve as an example. See AFXTLS.CPP's and search for "CriticalSection".

Good Luck,
Steve

What is C++ STL?:
STL stands for Standard Template Library and is a part of standard C++ libraries. It contains many useful data structures (containers) and algorithms, which can spare you a lot of the time. Today we will look at the STL Vector.
